When Erynn questions her "so now you like 'MC'? You never even talked to him...", Alexis thinks "that's not true..." and remembers the kiss.
I can only read that as her internal justification as to why this relationship is deeper than just "he is hot", otherwise...
It's a flawed choice, because on the surface she's offering no strings attached sex, except she's well aware that there are strings (that applies not just to the airplane but every scene before her reveal).
Also aware that it may create problems not just for her but for him too, add that to the list of shitty things she did.
Well... in the so called secret path she hasn't done anything shitty(yet), there's barely any interaction, so how can we confront her about being a shitty person/friend?
It sure will be nice if she puts the moves on her sister almost boyfriend, that will take the uber-shitty person cake lol.
So are you Nyx or not? And why so edgy? Take it easy and keep up the good work on all the ways i can make Alexis cry
